Indicator C5 — Pattern Consistent with Contract Splitting

AI-verified / Na-verify ng AI Data as of October 21, 2026

Pattern Consistent with Contract Splitting

Multiple similar contracts to the same contractor/DEO just under a threshold in a short window.

This is a statistical anomaly or indicator worth examining — not proof of wrongdoing, fraud, or corruption against any person.

Indicator: 4 contracts awarded to ROBETH CONST AND DEV'T CORP FORMERLY: ROBETH GEN MDSE CONST & SUPPLY by the same office started within 0 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 4 in the same municipality. It is common for large river or flood control projects to be split into several contracts for different sections or barangays for logistical or budgetary reasons.

This is a textbook C5 indicator: four contracts, all just under the ₱50M threshold, awarded to the same contractor by the same DEO, started on the same day, and all in the same municipality. The titles indicate different sections/sites (Sampao Section, D'Lotilla - Bual, Impao - Allah Bridge, Kolambog - Bambad), but C5 is specifically about clusters in one municipality, not about duplicate works. The code already confirmed the contracts are in the same municipality and within the cost/time window. There is no data artifact or error.
